4 Claims. (Cl. 131-12) This invention has to do with a tobacco pipe, and it is concerned particularly with certain improvements in a tobacco pipe designed to afford improved qualities in smoking. To this end a structure is provided which aiords passageways for the smoke in which the smoke is materially cooled and in which the products of condensation are trapped so that Vthe smoke which is drawn from the pipe by the user is clean and cool.

The invention also contemplates an improved structure which is believed to be particularly applicable and useful in a corn-cobl pipe. `Corncob pipes are preferred by many smokers. are necessarily cheap, and by the use of the improved structure herein recited and claimed, the quality yof the smoke which may be obtained in a corn-cob pipe is improved and believed tobe as good as that obtainedfrom the more expensive pipes.r Obviously, however, the inventionis not limited to corn-cobpipes, as the improved structure may beincorporated in a briar or other type of pipe. Y

Fig. 8 is a view with-portions cut away and portions in section of the form shown in Fig. 6.

The particular pipe structure shown in the drawing is modeled after a corn-cob pipe and will be so described. The center of the cob is cored out to form a bowl for the tobacco 1, leaving the body or walls 2. The center is'also cored out rto'form a compartment 3 and a partition 4 is allowed to remain between the compartments l and k3. This partition may be of the usual materialor pulp of the cob. An aperture for smoke is provided in the partition, as illustrated at 5.

thus connecting the compartments 1 and 3. The

stem 6 projects through the wall 2 and communicates into compartment 3. Compartment 3 is closed by a plug, which is preferably removable,

They,

as illustrated at'l, and this plug may be attached tothe bowl of the pipe in any suitable manner.

`Within the `compartment 3 is positioned an element designed to spread the .smoke out ,into relatively thin sheets or streams and also designed to entrap the products of condensation. This 'element preferably takes the form of a member which will be described herein as being of corrugate form. Any suitable'material may be used, preferably metal. The shape ofl this element is illustrated in Fig. 2,*With its ends 8 and 9 advantageously formed tov substantially abut against the bowl, and with the intermediate portion of corrugate or serpentineV form having portions 10 substantially traversing the com#Y partment 3y and portions '11., which may be rounded, and connecting adjacent' portions 10. This member maybe of springs material so that it tends toV expand, thus to engage the walls of the compartment 3 and retain itself in position tightly so that there is no looseness.

The smoke passes through the aperture 5, as illustratedv in Fig. 3, and into the compartment 3.y Here the smoke is dispersed or spread out as it passes through the compartment to the stem 6.` Thereis preferably a little clearance, say one or two thousandthsof an inch, between the edges of the portions ofthe corrugate element and the partition 4 and plug 7, these spaces being shown in an exaggerated manner at 12 and 13. the compartment more or less atrandom` and since its width is less thanthe depth of the compartment these spaces are provided. The smoke spreads out and vsome of the smoke moves through the compartment, by passing through p the spaces 12. The smoke partakes of a swirling action in the spaces 14 as illustrated by the arrows in Fig. 3. The samething is true of the smoke which passes through the passageways 13 on its way to the stem, as also illustrated by the arrows. The rounded portions lland the ends 9 of the element do not make an air-tight contact with the walls of the compartment 3 so that some of the smoke in passing through the compartment 3 moves around the ends and intermediate rounded portions of the corrugate element, part'akirigof a swirling action in the spaces 14, as illustrated by the arrows-inFig. 2.

Thus it will be observed that the smoke is The corrugate member, may be .placed in spread outinto several sheets or streams, each n tion, a separate partition element is provided.r

dissipated into the walls of the pipe, including the partition and the plug, and dissipated into the corrugate element, which in turn contacts with the walls of the pipe. Also the products of condensation are entrapped and collected in the spaces 14 and around the corrugate element and much of these products of condensation collect on the corrugate element. Obviously also the products of condensation collect on the walls of the compartment 3. The condensing action is facilitated by the cooling of the smoke. The result is cool, clean smoke passing into the stem 6.

It will be observed that the structure is one cheap to manufacture, and to this end is adaptable for use in a corn-cob pipe. Practically they only additional elements over the usual corncob is the provision of the corrugate element and the plug 7. As mentioned above, however, this arrangement may be used in briar pipes or the like.

This cooling of the smoke and the collection of products of condensation in and around the corrugate member effectively prevents, it is found, the presence of what are known as slugs, which often enter the stem'of apipe and reach the mouth of the user, much to the users discomfort. The plug 7 may be removed and the corrugate element may be removed from time to time, as suits the convenience of the user, for cleaning purposes.

In the form shown in Fig. 4 the variation resides largely in the partition, and except for the partition the reference characters are the same as in the form shown in Fig. 1. In this form the partition 15 is provided with two apertures 16 extending into the compartment 3, in which the corrugate element is disposed, and these apertures are in the portion of the bowl next adjacent the stem. The stem communicates with a passageway 16 extending through the partition, substantially in the plane thereof, which passageway 16 connects into the compartment 3 through an aperture l1'7. In 'this form the smoke, it .will be observed, enters the compartment 3 near the stem, traverses the `compartment and enters the passageway 16, which is inr alignment with the stem on the far side of the bowl.` This increases the length of travel of the smoke but due to the provision of the several apertures requires more` work and results in a more expensive structure.'

A similar arrangement is shown in Figs. 6, '7 and 8 except that here, instead of having the pulp or material `of the bowl provide the parti- This element may be in the form of a metal disc or plug, such as aluminum, and one portion may be elevated with respect to the other as at 21 and provided with horizontal passageways 22.

\ These connect with vertical passageways` 23 which lead into the compartment 3. The partition element has a passageway 26 corresponding to the passageway 16 of the form shownin Fig. 4, and an aperture 27. The smoke traverses the compartment 3 in the same manner as it traverses the compartment 3 in the form shown in Fig. 4. The metal plug may be covered with a layer of asbestos 28 for heat insulating purposes and for protecting the metal from the burning tobacco.

Where the partitions are provided by unremoved portions of the corn-cob it may be desirable to reinforce them so as to prevent them from breaking or burning out. 'Ihis may be done by covering or reinforcing the partition from above or from below, or both, by the use of a suitable plastic material such as plaster of Paris or a commercial product known as iron cement.. Plaster of Paris and Portland cement mixed substantially half and half has been found suitable for this purpose. The iron cement, however, serves admirably well and it is found that this cement readily carbons over, thus facilitating good flavor to the smoke.

The characteristic which the iron cement has for readily becoming carboned makes' this substance admirably suited for use in the bowl of the pipe. The walls of the bowl, including the tobacco chamber, as well also as the compartment below the chamber, may be covered with this iron cement. To make the matter more definite it may be stated that the side walls of the bowl, both above and below the partition, and the partition and the closure 7 may all be coated with such cement. A pipe thus provided becomes very nicely broken in with only a few smokings. The iron cement referred to is one which contains iron filings. rI'here are various iron cements available and their ingredients vary insofar as the elements other than iron filings are concerned. One example of such an iron cement, giving the proportions of the ingredients, is as follows: Clay-10 ounces; iron filings-4 ounces; salt-1 ounce; borax-l ounce; and black oxide of manganese- 2 ounces. Another cement or iron cement which may be used is one embodying silicate of soda. A paste may be made of silicate of soda with a quantity of iron lings in the paste and this may be used to coat interior portions of the pipe.
